VALVE.

Specification of Letters Patent.

Patented June 16, 1914..

Application filed November 26, 1913. Serial No. 803,292.

To all whom it may concern:

Be it known that I, EDWARD J. MASTER- SON, a citizen of the UnitedStates, residing at Elizabeth, in the county of Union and State ofNewJersey, have invented new and useful Improvements in Valves; and I dohereby declare the following to be a full, clear, and exact descri tionof the invention, such as will enable 0t ers skilled in the art to whichit appertains to make and use the same.

' This invention has relation to valves, and has for its objecttoprovide a valve particularly adapted for use in conjunction withsafety railway appliance described and claimed in my application Serial#787,636, although it is not necessarily limited to such use.

Another object of the invention is to provide improved devices adaptedto retard the movement of the piston.

In the accompanying drawing wherein is shown a practical and approvedembodiment of the invention Figure 1 represents a vertical sectionalview through the valve, partly brokenaway. Fig. 2 represents a sectionalview partly broken away of the shell and plunger taken at right anglesto Fig. 1. Fig. 3 represents a sectional view on the line 3-8 of Fig. 2.

Referring to the drawing in detail wherein similar reference numeralsdesignate corresponding parts throughout the severalviews 5 indicates abody of the valve having a central chamber 6, and transverse passages 7and 8 intersecting the chamber 6. A shell 9 is snugly fitted within thechamber 6 and is formed with longitudinal ribs 10 adapted to fit withinsimilarly shaped channels in the wall of the chamber 6 providing anon-rotatable mounting for said shell. The shell 9 is formed withdiametrically opposed openings registering with the passages 78.-- Alunger 11 is mounted for longitudinal "movement within the shell 9 andis provided I adjacent its lower end with an opening 12 adapted to bemoved into registration with the passages 7 and 8 and establishcommunication between them as will be understood.

The plunger 11 is prevented from rotating w1th1n the shell 9 by a pairof diametrically opposed and longitudinally extending ribs 13 working insimilarly arranged and shaped channels 14 in the shell 9. A suitablenumber'of balls 15 are movably mounted in recesses 16 formed in the ribs13 and are resiliently pressed against the walls of the channels 14 bysprings 17 Notches 18 are formed in the outer Walls of the channels 14;adjacent the opposite ends thereof and are adapted to receive portionsof the balls 15 as the plunger 11 is moved to either limit of itsmovement thereby preventing plunger from being casually moved from openor closed position.

One end of the chamber 6 is open and screw threaded and provided with acap 19 having a suit-able bore to receive the stem 20 of the plunger 11adapted to be manually operated by a handle 21 attached to the exposedend of the stem. An opening 22 is formed through the opposite end wallof the chamber 6 and is adapted to receive a suitable plunger or fluidpressure to automatically actuate the valve.

What I claim is:

A valve comprising a body having passages therein, a chamber in saidbody, a shell secured in said chamber having longitudinal channels inits inner face and notches in the outer walls of the channel adjacentthe opposite ends thereof, an apertured plunger slidable in said shell,ribs formed lon itudinally of said plunger seated in said 0 annels andhaving recesses adjacent the opposite ends thereof, and spring actuatedballs i EDWARD J.
